Why did you install it on the HDD in the first place? 64GB of SSD is plenty of space for Ubuntu OS + homedir. Then put all bulk data on the HDD.

Because over the time.. I dont want to waste time transfer up and forth between hdd and ssd. Plus.. Ssd got a limit where it always break after the write erase limit. N i already damaged one after a two years of usage due to the fact i used matlab. It tooks a lot of space to keep all my laborataries data.

No. If you want SSD cache-ing you can use bcache as noted in some other questions on site. Intel SRT is a Windows only technology, but bcache is in software not hardware and supposedly provides similar performance gains.

mdadm is for Raid as far as I am aware, not for cache-ing.

Correct me if im wrong, but for caching to be done.. We must raid the ssd 1st right? I bought this motherboard n ssd with all great feature it said it can give. If it cant be exploited fully by using ubuntu, should i consider swapping onto windows?

@hbdgaf Also read the link provided by aknelkaiser. It clearly shows Intel states that you can use mdadm and dmraid for Intel RST technology. I'm not aware of that and it seems very unlikely this is correct. It also lacks how exactly to use these utilities for RST. As far as I know they are not compatible with other than standard fake-RAID from Intel.
